Will I be getting a beeter fuel economy with a sri and a tip???

umm you should i would think, but maybe at cruising speeds 100km/h - 110km/h might see it be the same as standard as the tip may bring boost on sooner and therefore when sitting at 2500 - 2700rpm could be in the spool zone.
It's also the way you drive after the mods, i know cause i was getting 10 - 10.5l/100km standard now after all the work im getting similar maybe .5 worst occasionally, but all because i love the sound at mid range lol. If i drove like i used to I could manage low 9's but its not worth it lol

My economy went to shit when I had my intake and DP installed. But that was because I started driving it very differently once I could hear the induction noise. Highway economy actually improved quite a lot for me.
Then when I got it tuned it improved quite a bit, but the induction noise is still a bit too tempting to pass up sometimes. fwhoooosh!

I haven't noticed a difference to be honest. Prior to installation of my SRI/TIP I was averaging around 480-510, and currently I'm averaging around the same, maybe just a bit better. I think it's as Bakis stated where it depends on the way you drive. The MPS fuel average is stated to be approximately 10.5l/100km.
In theory it's designed to produce better economy due to improved fuel burning but who knows.

I noticed a slight improvement with SRI install. Even more so with CBE.
But as others have said above: I push the car more now to hear the 'wooshkaa!' of the intake and the barking exhaust. Especially driving past concrete walls and in tunnels![]()

Damn you people and your loud exhausts.
Oh the woes of being a Uni student, can't afford SH*T.
Looking forward to that tax return, gonna get me that downpipe that's been hounding my dreams. (You know you're car crazy when....)

Some people come into our lives and quickly go. Some stay for a while, leave footprints on our hearts, and we are never, ever the same.

My trip computer says I have got a 9.9/100 since I have owned the car and I have a SRI.
On the freeway I have extracted 550+ before. Normally get about 420ish.
